LUBRIGA'IOB FOR PISTON-RODS.

rod.

More particularly defined, the invention consists in forming an annularplate in two halves suitably secured together and in providing them withstiffening and strengthening ribs.

In carrying the invention into practice it is preferred to secure thetwo halves to-- gether by screws or the like, and to form the platehollow on the side facing the stuffing box. The plate is mounted againstthe coverof the box and is drawn against it by tightening of the boltsof the stufling box which are made to pass through said plate. Also aduct is formed in the plate itself to connect the pad to an oil pot orother lubricator. I

An embodiment of the invention is illustrated in the accompanyingdrawings in which Figure 1 is a sectional elevation through the stuffingbox showing the lubricating device in position. Fig. 2 is a plan view ofthe lubricator detached and Fig. 8 is a section thereof on line IIIIIIof Fig. 2, looking in the direction of the arrows.

The lubricator consists of a hollow plate, preferably made in two halvesl, 2, connected together by screws or the like 3. Ribs 4 connecting theupstanding concentric inner and outer walls 12 and 13 are cast atintervals around the annular plate to strengthen the same. A duct 5 isarranged for the purpose of connecting a lubricating pipe 6communicating with the supply of oil, such as reservoir 7. An annularpad Sof suitable packing material is carried by the annular plate 1, 2and is continuously kept su plied with lubricant from the reservoirOutside the inner wall 12, the

plates 1 and 2 are grooved to form a circular channel 14 to accommodatesurplus lubricant. This channel is continuous, the ribs 1 being suitablyformed to this end, and is in connection with the pad 8, by theperforations 15.

The hollow plate 1, 2 is preferably made open on the side adjacent tothe stufling box and in use is secured by the bolts of the stufling box.Holes 9 are provided on the plate 1, 2 for the purpose of allowing thebolts 10 of the stuffing box 11 to pass through. It will be seen thatwhen the lubricator is placed over the ends of these bolts and the nutsare drawn up, the lubrioator is firmly held in position and isnevertheless readily removable when desired.
